A Controllable Efficient Content Distribution Framework Based on Blockchain and ISODATA

In this paper, we focus on the efficiency improvement of the content distribution network while endow this framework with controllability, where CHs(Content Helpers) have restricted distribution scope and thus the economic benefits of CP(Content Provider) are protected. We propose a novel controllable content distribution framework by using the blockchain technology as well as the iterative self organizing data analysis techniques algorithm (ISODATA), which is an improved k-means clustering method. To implement an incentive and consensus mechanism utilizing proof-of-stake, we employ smart contract to enforce content distribution in an autonomous way. We conduct some experiments to verify the validity and feasibility of the proposed framework. The experimental results demonstrated show that our framework has the advantages of high efficiency, low latency, and good scalability.
